Specification of Letters Patent.

App1ication p1cd September 27, 1911. Serial No. 651,664.

To all whom it may concern:

Be it known that I, Join: BOOTH, a citizen of the United States,residing at Peru, in the county of Miami. and State of Indiana, haveinvented a new and useful Desk; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a new and useful combination desk andtypewriter cabinet.-

The main object of the invention is to provide a roll to desk having acompartment to one side or the reception of a typewriter, which issupported upon a platform slide, slidably arranged in the compartment.

A feature of -the invention is the provision of a shaft having a pairofspring tensioned arms," for raising the platform, as

it is withdrawn from the compartment.

A further feature of the invention is the provision of a door having anextension leg, for supporting the platform slide when withdrawn, whichdoor also closes the compartment.

A further feature of the invention is the provision of means for lockinga plurality of drawers upon the other side of the desk, when the top ofthe desk is closed, and when the top is opened, the locking means isactuated to release the drawers.

The invention comprises further features and combination of parts, ashereinafter set forth, claimed.

In the drawings :F igure 1 is a view in perspective of a desk,'embodyingthe features of the invention. Fig. 2 is a sectional shown in thedrawings and view on line 2 2 of Fig. 1, showing the platform slide in alowered position in the compartment.

Fig. 3 is a similar view, showing the platform slide withdrawn from itscompartment. Fig. 4 is a sectional view on line 44 of Fig. 1, showingthe locking means for the drawers. Fig. 5 is an elevation showing asectional desk. Fig. 6 is an enlarged detail View of a portion of thedesk in Fig. 5. Fig. 7 is an enlarged detail view of a portion of thedesk in Fig. 5. Fig. 8 is a detail view of the plates 16*.and 16. Fig. 9is a detail perspective view more clearly showing how the arms, the rod9, the springs 10 and the ears 9 are arranged.

Referring more especially to the draw- Patented Mar. 4, 1 913.

members 4, having laterally extending elongated lugs 5. Also.surrounding the shaft 3 is a pair of torsional springs 6. One end ofeach spring engages the bottom of the compartment, as shown, while theother ends bear slidably against the laterally extending elongated lugs,as shown at 7, so as to tend to hold thearms 4 in the position shown inFig. 3, in which positions the platform slide 8 is held raised andextended out from the compartment.

'A plate 9 having guide flanges 9 is provided. This plate has ears 9projecting downwardly from its under surface, in which ears, a rod' 9 isloosely journaled. This rod 9 is also fixed at 9 in the outer ends ofsaid arms, as shown clearly in Fig. 9. Owing to the ears being looselyjournaled on said rod 9, the plate 9 is allowed a slight pivotal actionrelative to the rod, such pivotal action being limited only sufficientlyby the springs 10, in order that the platform and the plate 9 are heldsteady and in approximately horizontal positions, when lowering the armsand retracting and extending the platform. The springs 10 are coiledabout and fixed to said rod 9 at their coiled portions, as at 9 Saidsprings 10 are also arranged, one between each of the arms 4 and each ofthe ears 9 When raising and extending the platform, the spring arms onthe left of said springs 10 are under greater tension, and when loweringthe arms 4 and receding the plat-form, the spring arms on the right ofthe springs 10 are under greater tension, thus steadying the platformand holding the same approximately horizontally.

When the platform slide is'ina raised extended position, the samecontacts with the shoulder 11 of the compartment. The platform slide isprovided with the usual means 12, for securing the typewriter (shown indotted lines) in position.

A suitable door 13-, hinged at 14, and .provided with an extension leg15, is provided, and designed for closing the compartment.

However, when the platform slide is raised and withdrawn from thecompartment, the door 13 is swung o n, so as to constitute a support forthe sli e, shown in Fig. 3.

The other side of the desk 16 is provided with a compartment 17 for thereception of a lurality of drawers 18. Incidentally a locfiiing meansfor the drawers when the top of the desk is closed is included incombination with the desk casing. This locking means consists of astandard 19, which is arranged to slide vertically for a short distance,there being shoulders '20 and 21 to limit the standard in its movement.The constricted portions 22 and 23 beyond the shoulders penetratethrough the top and bottom of a compartment 17, and between the shoulder20 and the bottom 24 a coil spring 25 is arranged. This springconstitutes:

means for holding the standard in its raised position, and the shoulderin contact with the top of the compartment 17. This spring also holdsthe lateral projections 26 of the standard 19 in engagement with therecesses 27 of the projections 28 of the drawers 18,

that is, when'the top 29 of the desk is closed. When the top-29 is open,however, the projections 26 are thrown from engagement with the recesses27, by virtue of the rear end of the top coming in contact with thelateral lug 30 of the constricted portion 23 of the standard, whichforces the standard down againstthe action of spring 25.

From the foregoing in conjunction with the annexed drawings itwill benoted that there has been devised a novel, simple and eflicient cabinetor desk, for containing a sliding platform on which a typewriter isadapted to be supported, and one which has been found to be practicalfor this purpose.

In the forward lower portion of the compartment 2 is a latch 32 toengage the platform slide to hold the same and the arms 4 down againstthe actions of the springs 6. The arms 4 are connected by a bar 33, sothey will move to ether. In Fig. 5 the si es or pedestals 16 of the deskhave plates 16, counter-sunken theres in and secured in place by thescrews 16 These plates are provided with knuckles 16", which arereceived between the knuckles 16 of the plates 16. The plates 16 arealso counter-sunken in the upper portion of the desk and secured theretoby the screws 16.

Cotter pins 16 are passed through the '55 knuckles 16 and 16 forsecuring the plates together, thereby connectingthe u per portion of thedesk to the sides or pe estals.

The sides or pedestals are provided with socket, members 17", havingtransverse pins 17 The front and back portions 17 and 17 of the desk areprovided with plates 17 having hooks 17 which are designed to engage thetransverse pins 17", for holding the ront and back portions of the deskto the partment, ashaft journaled in the rear lower portion of thecompartment, a pair of arms having a bar rigidly connecting themtogether and pivotally mounted on the shaft, torsional springs arrangedon the shaft and disposed and constructed to raise the arms,

a plate having guides at each end and provided with ears projectin fromits under surface, a rod journaled in said ears and fixed in the freeends of the arms,thus pivotally mounting the plate on the rod, a springarranged adjacent each end of the rod an coiled about and fixed to saidrod at its coiled portion, and arranged one between one arm and one earwith its free ends bearing with suflicient pressure against the undersurface of the plate to steady the same and hold it approximatelyhorizontally when the arms are being adjusted, and the platform mountedin the guides of the plate and adapted to support a typewriter, means toengage one of the arms for holding said arms and the platform down inthe compartment, said platform when extended and the arms raised adaptedto rest upon an opened closure of said compartment for sup- I portingthe platform.

In testimony whereof I have signed my name to this specification in thepresence of two witnesses.
